Do you blame a certain class of investor for being extremely risk-averse? Imagine if you're managing people's retirement money. How would you invest it? People's nest eggs. To put it into computer-nerd context; remember the saying, "nobody ever got fired for buying IBM". Isn't this the same kind of thinking? By the way, what do you think about the idea some are proposing that crypto-currencies are more solid than a gold standard? Instead of transitioning from this central bank backed fiat currency malarkey (which in theory ought to work just fine but doesn't because of greed, collusion, corruption, hubris – i.e., human weakness) back to the gold standard, some say we should move to crypto-currrency standards. I'm not at all versed enough in the tech and theory to know if this is a good idea or not.
